Question

An ice cube holding an iron nail in it is floating on water when it melts the water level Rises.

• A. True
• B. False

Answer 1

The correct option is B False

1. The combined density of ice and iron nail is less than that of water. That is why the ice cube with iron nails floats.
2. When the ice melts, the iron nail no longer is able to float above water and sinks.
3. At this time the volume of water displaced by the metal piece that has sunk is equal to just the volume of nail.
4. Hence the volume of water displaced by nails reduces on melting of ice.
5. Thus, the level of water will fall after the melting of ice.

Hence, the given statement is false.
